Air dispersion modelling is a method of simulating the transport and transformation of air pollutants in the atmosphere. It assesses the impact of emissions from various sources, such as industrial plants, vehicles, power stations, and fires, on air quality and human health.

Quantum Air uses the Atmospheric Dispersion Modelling System (ADMS). TThis allows modelling of the dispersion of pollutants emitted continuously or intermittently from point, line, area, or volume sources. It can account for the effects of complex terrain, buildings, coastlines, and meteorological conditions on the dispersion process. It can also include the methods of dry and wet deposition, chemical reactions, radioactive decay, and odour perception.

ADMS can produce outputs such as pollutant concentrations, deposition rates, and plume visibility at various locations and times.

The output of such computational modelling is a crucial planning stage process to enable the future operational air quality impacts of the proposed development and the effectiveness of mitigation to be demonstrated.
